   Abstract:
   A new approach to optical clock distribution utilizing optical waveguide interconnect technology is introduced. In this paper, we develop a new algorithm for design and optimization of board-level optical clock distribution network for high-performance optoelectronic system-on-a-packages. The optimization approach takes into account bending and propagation losses of optical waveguides. Less than 26.1psec in signal timing skew is obtained for a signal flight time of 614.38psec. About 15% reduction in optical power consumption is also obtained over clock nets routed with existing (optical) methods.
